Properties:

HPMA iri yakaderera molecular uremu polymeride, ane avhareji molecular uremu 400-800. Hapana chepfu, inonyungudika mumvura, makemikari akakwira uye kugadzikana kwekupisa, tembiricha yakaora inopfuura 330 ℃. HPMA has obvious threshold effect under high temperature (350℃) and high pH（8.3）level, suitable to be used in alkaline water system or built with agents. It has good scale inhibition against carbonate and phosphate scales under temperature 300℃ with effective time as long as 100 hours. Due to its good scale inhibition and high temperature tolerance properties, HPMA is widely used in desalination plant of flash vaporization equipment, low pressure boiler, steam locomotive, crude oil evaporation, petroleum pipeline, and industrial circulating cool water systems. In addition, HPMA has good corrosion inhibition effect when used together with zinc salt. HPMA inogonawo kushandiswa sekuwedzera kune simenti.

Tsanangudzo:

Items	Index
Chitarisiko	Pale yellow to umber transparent fluid
Solid content,%	48.0 min
Bromine kukosha, mg/g	50.0 max
pH (1% mhinduro yemvura)	2.0-3.0
Density (20 ℃), g/cm³	1.18 min

Kushandisa:

HPMA is usually used together with organic phosphonate at dosage of 1-15ppm for circulating cool water system, oilfield fill water, crude oil dewatering and low-pressure boilers. HPMA ine chikero chakanaka inhibition (98%) uye chiyero chekubvisa zvivakwa. Kana yakashandiswa pamwe chete nemunyu we zinc, inogona kuvharisa kabhoni simbi corrosion.
